About Marianne

Marianne Blackstone Tabner is passionately curious about science and nature. She loves the outdoors, especially the coast of San Diego and New England. She especially gets excited about empowering young girls to "Be the change they wish to see in the world."

Marianne loves writing and researching nonfiction and fiction with STEM and STEAM themes in picture books and middle-grade books that use her professional background as a former special education teacher to spark fascination, entertain, and inspire children to learn more about their natural world.

Her self-published debut picture book Taking Turns (2020), offered in both English and Spanish, helps children explore concepts of sharing while providing them with opportunities to expand their creativity and imagination with hands-on science activities.

Her upcoming picture book The Last Lighthouse Keeper, coming in fall 2027, tells the story of a lighthouse keeper who must adapt when new technology changes how ships navigate the coast.

She holds a certificate in Writing for Children from UC San Diego (2020) and a B.S.Ed. in Elementary/Special Education. Marianne is represented by Stephen Fraser of the Jennifer De Chiara Agency out of New York and Los Angeles.

When she is not writing, you can find her reading a book with kids, nature walking along the coast, playing pickleball, cycling, or traveling to discover new faraway places.
